Shrinking mountain snowcaps. Dwindling aquifers. Lakes reduced to ponds, ringed by enormous parched shores. Cities enforcing drastic water-use restrictions.

In the U.S., parts of the West and Southwest are experiencing what Gale Norton, former Secretary of the Interior, has called "perhaps the worst drought in 500 years."
